CS 162 Spring 2000 Assignment 3 –Object-Oriented Programming with C++ - Using an existing class 100 points

Assigned: 02/14/2000

Due: 02/21/2000 at the start of class.

Pre-Lab (Do Before Lab): Bring an empty (or nearly empty) disk. Plan out steps needed for program.

Pairs: You may work in pairs if you want. Note, during the course of the semester, you cannot pair with any one person more than twice. If you work in a pair, turn in ONE copy that is the work of both of you, with both of your names on it. Each member of the pair will receive the same grade for that lab. In such a partnership, students must share as equally as possible the work and learning. Working together with truly shared effort and learning can be a positive experience. However, simply giving/receiving code from someone defeats the learning process. If substantial parts of a program are taken from non-partners, that is plagiarism. The copier and copyee will each receive a zero.

Main Assignment:

A simplified Account class has been provided (account.h and account.cpp under Review on my WWW page). Create a (very) simplified client program, as illustrated below. The program should create an array of 10 accounts, and as long as the user wants to keep playing, prompt them for an account number, and when they give a valid account number, ask them if they want to Deposit, Withdraw, or Check account balance, or quit. After each account quits, see if the general user says to quit (see below). When quitting entirely, show all 10 account balances.

Details:

  1. If you change account.h and/or account.cpp, make sure you hand them in as well. (I don’t think you should have to – I don’t think you should even have to look at account.cpp)
  2. You can get the random account numbers using the default constructor.

Hand-in:

1) Listing of the program

2) Disk with your .cpp file and your working .exe file. NAME YOUR PROGRAM FILE yourlastname3.cpp; Name your project yourlastname3 so that the executable will be yourlastname3.exe. If you are working in pairs, use both last names (e.g. redmondsmith3.cpp)

Miscellaneous:

1) If you have any questions about what should be done, please ask!!

2) MAKE SURE YOUR PROGRAM WORKS! (i.e. more than just removing compile errors). Test it more than once - I will!

3) Remember: Indentation, meaningful variable names, symbolic constants, and meaningful comments. Weaknesses in any of these could result in points off. Also make sure you put YOUR NAME(s), section, and e-mail address in comments at the beginning of the program.
